The pump, pipes, and seals in a spa hot tub may dry out after prolonged periods without water, accelerating aging. Some materials require a certain level of moisture to maintain elasticity and sealability. If these components are exposed to air for extended periods, they may crack or lose their function, shortening the lifespan of the spa hot tub.

To reduce the risk of rainwater falling directly into your hot tub, consider installing a canopy, tent, or retractable awning over the tub. This not only effectively prevents rain from entering the tub but also protects electrical components from moisture, increasing safety.

Outdoor spa hot tub structures and heaters are designed to operate at specific water temperatures. Frequent use of extremely cold ice cubes may damage components such as the heater and pump due to the extreme temperature fluctuations.

A common infection caused by low bromine levels is "Hot Tub Rash", a skin disease caused by Pseudomonas aeruginosa.
